DHCP for static leases is good when you have a few machines and change
settings like DNS or gateway addresses for example. Saves having to go
to every machine change settings. Or you want to do a wholesale change
to a network....from 192.168.1.xxx to 10.10.xxx.xxx network (netmask
would get changed in this example as well)
As for the error......I've seen that come up when I've installed
linuxcnc on slackware. If you aren't too concerned about security you
can change the permissions on the iptables binary.

Once you already have DHCP how much extra work is it to make the IP
lease
fixed? One or two mouse clicks. Then you have a central place to do
all
the IP assignments and there is little chance to using the same IP
twice.
You're still talking about mobile devices. Do you consider a CNC
machine a mobile device?
The "D" in DHCP is for "dynamic." Why bother with it when you can set
the IP address statically at build/configure time once and you don't
have to worry about it again? It's not like you're going to take your
CNC machine to Starbucks with you. A few clicks on your DHCP server
and you can set a range of static IP addresses too.
